As for determining which animals have been strangled and not drained of their blood, we must understand that the focus was on the quantity of blood remaining in the meat of the animal. It was not the fact that the animal was strangled that kept it from being eaten, but the fact that it was never drained of its blood.
The Eocene constitutes the middle part of the Paleogene period (65-23 million years ago), preceded by the Paleocene and succeeded by the Oligocene epoch (34-23 million years ago); all of these periods and epochs were part of the Cenozoic Era (65 million years ago to the present).
= mega-annums or millions of years Phanerozoic time is subdivided into 3 Eras: Paleozoic Era (543 Ma to 245 Ma) interval of old life Mesozoic Era (245 Ma to 65 Ma) interval of middle life or age of dinosaurs Cenozoic Era (65 Ma to present) age of modern life or age of mammals.
